As water pressure builds on one side of the AquaDam®, the pressure displaces the water in the inner tubes. However, because the inner tubes are unable to move, the AquaDam® assumes a position of equilibrium and behaves as a solid dam.
In order to move or tip a filled AquaDam®, the maximum recommended working depth would have to be exceeded. Too much water pressure against the side may cause the entire AquaDam® to slide or tip sideways, depending on the nature of the surface and friction factor it is placed on. It would be technically impossible for one tube to roll completely over another in a filled AquaDam.
